HEATING-STOVE.

. SPECIFICATION forming part of Letters Patent No. 508,962, datedNovember 21-, 1893.

Application filedApril 28, 1893. Serial No. 472,252. (No model.)

To all whom it may concern:-

, Be it known that I, AUGUST lVIU'LLER, builder, of 6 Alexanderstrasse,Hanover, in the Kingdom of Prussia and German Empire, have invented newand useful Improvements in and Connected with Stoves for Heating Rooms,Conservatories, and Like Spaces,'of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to that class of. heating stoves which areadapted to humidity as well as to warm the air of the room, conservatoryor other space in which they are placed, whereby theevil effectsattending the presence of a highly dried atmosphere are avoided and theinvention consists of an improved construction and arrangement of suchstoves.

In the annexed drawings, Figure 1 represents a front sectional elevationand Fig. 2 a side sectional elevation of a stove constructed accordingto my invention. Fig. 3 represents a cross section of the apparatus,taken upon the lines A' B, Figs. 1 and 2.

Upon reference to the drawings it will be seen that my improvementsconsist essentially in an improved arrangement and disposition of awater heating space relative to the heat radiating fine of a stove ofthe above mentioned type.

a designates a sheet metal heat radiating fiue, superimposed upon astove of slow combustion or other suitable type.

b is an outer sheet metal casing disposed around the flue a in such amanner that an annular space or jacket a exists between the metal'a andthe metal I). In the upper part of the casing b is a water space a whichcommunicates, by means of perforations provided around its bottom, withthe annular jacket a above mentioned. The casing a, is divided into twoside rising fines g by a central descending flue h.

The mode of action of my improved stove is as follows:-Within ten tofifteen minutes after the stove has been lighted, ebullition of steam inthe annular jacket a commences. The rising steam escapes into the roomor space being warmed through apertures c, and the air in suchroom isthereby humidified and warmed simultaneously. The exit of steam from thestove may be regulated by ad- 3' listing the cap 61 over the aperturesc,whereby the surplus steam may be allowed to escape through the pipefir The entire apparatus above described is mounted upon four rollerswhich may when desired run in rails adapted to receive them.

-When it is required to sweep the chimney In order to utilize the heatof the surplus steam generated by the stove, such steam may 4 be led toa receiver disposed (where a large room is to be warmed) in the sameroom as the stove, or the steam may be led to a' receiver disposed in aneighboring room; In these instances of theapplication of my inventionthe steam generating portions of the stove may be with advantagesuitably enlarged. A space containing thirty-five thousand cubic feetcan by the above described method of employing a a stove constructedaccording to my invention be heated at a cost of from fourteen tosixteen pence per diem.

Pine branches or other suitable fragrant, medicinal, or antisepticmaterials may *be placed in the water space c, whereby their fragranceor other property is disseminated throughout the space being warmed."

By the use of a stove constructed and operating asabove described, thetemperature of the room or other place in which it is situated may beraised to any desired degree while the necessary humidity of theatmosphere is at the same time maintained, and the deleterious effectsof-a dry heated atmosphere, so often produced by heating stoves as atpresent constructed, are prevented. The arrangement of flues g and hinsures a sufficient draft for the stove, while the constructionillustrated in the drawings, comprising as it does comparatively fewjoints precludes the dissemination of dust and dirt.

By virtueof the qualities above enumerated, my improved stove isparticularly suitable for employment in hospitals and like places, Whileits capability of producing a regulated humidity of atmosphere rendersits application to'the heating of conservatories and other placescontaining growing plants and the like, particularly advantageous.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

l. A heating stove consisting of a combustion chamber, a vertical fluehaving a water spaceencircling it, a Water chamber with perforationsleading to the Water space, and exit openings from said water chamberfor the escape of the steam, substantially as described.
